GAS BURNER I Filed June 29, 1931 Fatented Mar. 14, 1933 UNITED STATES PATENT orrlcs WILLIAM D. ANTRIM, OF GLOUCESTER, NEW JERSEXKASSIGNOR TO ROBERTS & MANDER STOVE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA GAS BURNER Application filed June 29,

The object of my invention is to improve the construction of burners for gas ranges so that the burner section proper can be applied to a mixing chamber section located below the burner section at different depths.

It will be understood that my improved burner can be applied to gas ranges forstoves using ordinary manufactured gas or special gases known as casing head gases. When ordinary manufactured gas is used the burner section can be located comparatively close to the mixing chamber and a certain distance away from the top of the stove, but when casing head gases are used the burner will be located at a greater distance from the mixing chamber section and the burner proper can be located comparatively close to the top of the range.

A further object of the invention is to make a bridge piece at the outlet end of the mixing chamber section, which extends into the passage of the burner section so as to deflect the gases as they pass from the mixing chamber section, preventing the gases escaping directly through the openings above the outlet passage in the mixing chamber section, preventing an excess of gas at this point, as it is desirable that the gas be so distributed that all the jets will be substantially even. By making the burner in two sections the neck of the mixing chamber section and the support for the burner section may be of any length desired. The burner section, after the parts are assembled, can be secured to the mixing chamber section and the support retains the burner section substantially level.

In the accompanying drawing:

turned to regulate the amount of air admit- V ted to the burner. In the center of the cap is an opening 5 forthe gas pipe. This cap is secured in place'after adjustment by a screw or other device. lower section of the burner are brackets ,7,

which in the present instance are slotted asfat 8. These brackets rest on the supporting bar of the range. 9 is the upturned'neck of the lower section of the burner having a reduced extension 10. This extension in the present instance is tapered and is ground so as to fit the ground surface of the dependingportion 12 of the upper section 11 of he burner, as clearly shown in Figs. 1 and 4. The upper section 11 consists of a hollow hub 14 and a series of hollow radiating arms 15, which are perforated at the top as at 16. The hub has an open center 17 which allows air to pass through the upper section to the up per surface of the burner. with the mixture of gas and air passing throughthe mixing chamber, so as to produce the proper flame required.

It will be noticed that the depending portion 12 of the upper portion is at one side of the opening 17 of the upper b'urner section 11, and in order to deflect the mixture of air and gas as it enters the burner section, a bridge 18 is formed at the end of the neck 9. This bridge piece extends into one side of the hub 14 and acts to distribute the mixture of gas and air to each side of the upper section of the burner and to prevent the gas passing directly to the openings 16 above the neck 9, so that the amount of gas escaping through the perforations 16 in the several arms of the burner will be substantially the same. In order to insure the proper relation of the This air mixes At each side of the bridge 18 to the opening in the upper section '7 Figs. 1 and 5. While the lug 19 is shown in the'upper section of the burner and adapted to a recess in a post on the lower section, it will be understood that the lug may be on the lower section, which would enter a notch in a depending portion of theupper section, without departing from the essential features of the invention. I

By. the above construction the neck 9 of the 1 mixing chamber section 1 may be "of any length desired and the supporting post 21 may also be of anylength, depending upon.

the character of gas used. In the present in stance the depending portion 12'of the upper burner. section is secured to theneck 9 by a pin '22, but other means of attachment maybe provided. The supporting post 21 not only 7 is for the purpose of holding the burner in a horizontal position but it also acts to prevent the turning of the burner sectionll ,on the neck and straining the pin.

By this invention the improved burner can be used for any type of gas and is particularlyadapted for use of gases from oil cracking,

known as casing head gases, and which consists for the most part of propane or butane,

- or mixtures of themand other hydro-carbons,

gaseous 'a troom' temperature. By adjusting the height vof the burner from the mixing chamber so as to bring the burner at a proper level in respect to the top of the range, complete combustion is assured, thus preventing the formation of poisonous carbon monoxide and at the same time furnlshing the proper Bi t. u. per hour (heat). I

While, this invention is particularly adapted for a burner for gas ranges, it will beunderstood thatit can be used in connection with ordinary gas plates and gas heaters '40 without departing from the essential features of'the invention. c

I claim: The combination in a gas burner, of a lower and anupper section, the lower section forming a mixing chamber and having an upturned neck, the end of the neck being tapered and ground, said neck'having a bridge piece located above the tapered portion, theupper section forming the burner proper and having ahollow hub and hollow perforated arms communicating with the hub and also having a depending portion fitting over the ground extension of the neck, the inner surface of the projection being ground to form a gastight joint between the two sections; means for securing the depending portion of the upper sectionto the neck; andmeans for supporting the upper section some distance from the neck. e
